Don't be afraid of sounding 'jaded.' the pictures accompanying the article made clear that however lacking the design of the pressure washer was, the accident had plenty of 'help' from the victim.

The best equipment will fail when used in the wrong way (for example, when the materials cannot stand up to the chemicals present) or when subjected to abuse. Just to clarify, I am including the building's electric as part of the 'equipment.'

Though I an sorry for the victim, and his survivors, at some point this becomes the "Darwin Principle" at work. Buy the wrong stuff, beat it to pieces, cobble it together with duct tape .... what do you think is going to happen?
